SWITCH-THROWING DEVICE.

Specification of Letters Patent.

Patented Sept. 8,1914.

Application filed. November 27, 1912. Serial No. 733,839. 7

vention is the provision of positive and re-' liable means, ashereinafter set forth, for

manually and simultaneously operating a:

semaphore and switch stand and a switch mechanism.

7 A further object of this invention isto provide a switch throwingdevice that is simple in construction, durable, easy to install andhighly eflicient for the purposes for which it is intended.

With the above and other objects in view the invention resides in thenovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein Figure 1 is a plan ofa switch throwing device in accordance with. this invention. Fig. 2 is across sectional view of the same, Fig. 3 is a side elevation of aportion of a switch stand, Fig. 4 is a cross sectional view taken on theline 117-11 of Fig. 2. Fig. 5 is a horizontal sectional view taken onthe line V-V of Fig. 3 and Fig. 6 is a detail.

Further describing my invention in detail with reference to theaccompanying drawing, wherein like numerals denote cor-- respondingparts throughout: 1 denotes ties or other supports for the base flanges2 of rails 3 and 4, said rails being held upon the ties by inner andouter rail fasteners 5 and 6. The rails 4 are provided with switchtongues 7 movable relatively to the rails 3 and said switch tongues areconnected by a brace 8.

9 denotes bearings secured, as at 10 to the base flanges 2 of the rails3, and journaled in said bearings is a shaft 11 that has collars 12 toprevent longitudinal displacement of said shaft. The shaft 11 has aspiral groove 13 and one end of the shaft has a pin wheel 14 whichconsists of a vertically disposed disk having projecting from one face a'circular row of lateral pinscapable of meshing with the teeth of ahorizontally disposed sector gear 28, the latter being carried by theshaft 25 to be hereinafter referred to."

The wheel 14 is more clearly shown in Fig. 6. V

l5 denotes T bars connected to the confronting sides of the switchtongues 7, adacent to the ends thereof, said switch tongues being of theordinary and well known type. Connected tothe T-bars 15 by rivets 16 orother fastening means are parallel connecting bars 17 and 18 connectedtogether by bolts 19 and nuts 20. Thebars 17 and 18, adjacent to theends thereof have U-shaped straps 21 extending under the shaft 11 andsaid straps are held by bolts 22 arranged transversely upon the bar 17.

23 denotes a depending pin, carried by the bar 18 that engages in thespiral groove 13 of the shaft 11 (see Fig. 4).

24 denotes a switch stand located at the side of the track and rotatablymounted in said post is a vertical shaft or rotary member 25 that hasthe upper end thereof provided with a lantern 26 and semaphores 27. Thelower end of the shaft 25 has a sector gear 28 that engages the pinwheel 14, said wheel extending into an opening 29 provided therefor atthe base of the stand 24.

30 denotes cranks carried by the shaft 25, above the post 24 and saidcranks are connected by a handle 31. Movably mounted in the cranks 30 isa latch 32 that is arranged in parallelism with the handle 31. The lowerend of the latch 32 is adapted to engage in notches 33 provided thereforin the upper end of the post.

By gripping the handle 31 and the latch 32 said latch can be shifted outof one of the notches 33 and the shaft 25 rotated and the latch placedin engagement with the other notch. The shaft 25 is locked in eitherposition. vVhen movement is imparted to the shaft 25, the shaft 11 isrevolved substantially a quarter revolution through the medium of thegear 28 and the pin wheel 14. WVith the pin 23 extending into the spiralgroove 13 the bearings 17 and 18 are shifted to simultaneously move thetongues 7 into or out of engagement with the rails 3, said tonguescontrolling the movement of rolling stock upon the rails 3 and 4. i

It is thought that the operation and utility of the switch throwingdevice will be apparent without further description, and while in thedrawings there is illustrated a preferred embodiment of the invention,it is to be understood that the structural elements are susceptible tosuch variations and modifications as fall within the'scope of theappended claims.

that I claim is 1. In a switch throwing device the combination withrails and switch tongues, of bars connecting said switch tongues, adepending pin carried by one of said bars, a shaft revolubly supportedbeneath said rails and having a spiral groove to receive said pin, a pinwheel carried by one end of said shaft, a switch stand at the same endof said shaft, a rotary member rotatably mounted in said post, a sectorgear carried by said rotary member and engaging said pin wheel foractuating the latter thereby rocking the shaft to shift'the pin and movesaid tongues, and means carried by said rotary member for engaging saidpost and locking said rotary member in adjusted position.

Copies of this patent may he obtained for five cents each, by addressingthe 2. In a switch throwing device, the combination with rants andswltch tongues, of T bars carried by said switch tongues, barsconnecting said T bars, a shaft rotatably mounted beneath said rails andhaving a spiral groove formed therein, a pin carried by one of said barsand extending in the groove of said shaft, a pin wheel carried by oneend of said shaft, a switch stand at the same end of said rotary member,a rotary member rotatably mounted in said post, a sector gear carried bysaid shaft and'engaging said pin wheel for actuating the latter therebyrocking the shaft to shift the pin to move said tongues, a handlesupported from said rotary member to facilitate moving said rotarymember, and a latch in connection with said handle for engaging saidpost and locking said rotary member in adjusted position.

In testimony whereof I afIiX my signature in the presence of twowitnesses.
